Specification of Letters Patent.

Patented 01a. 7, 1913.

To all whom it, may concern:

-Be it known that I, IVILsoN E. PORTER,

a citizen of the United States, residing at invention, with the bezeland crystal removed. Fig.2 a corresponding vlew w1th the bezel, crystaland dial removed. Fig. 3 a broken sectional view on the line wb of Fig.l, but also showing the bezel and'crys tal. Fig. 4 a corresponding viewon the line c-d of Fig. 2.

My invention relates to an improvement in watches, the object being toprovide for positioning the movement with respect to the case with anaccuracy heretofore unknown, and also to provide for positioning thedial Withrespect to the movement with a corresponding degree ofaccuracy.

My invention, I may add, is particularly designedfor use in that classof stem-Winding and stem-setting watches in which a winding-wheel and asetting-Wheel are permanently mounted upon a stem fixed in the pendant,and therefore organized with the watch-case into which the movement mustbe set so as to bring its complementary parts into mesh with the saidwheels on the stem.

But my invention is not limited to use in such watches and I wish to beso understood. a

With these ends in view my invention consists in a watch having certaindetails of construction and combinations of parts as will be hereinafterdescribed and pointed out in the claims.

In carrying out my invention as herein shown, I emplo three forwardlyprojecting hollow positioning-pillars 2 formed at their inner ends withbearing shoulders 3 and hollow rivets 4 which latter are passed fromfront to rear through positioning-holes 5 near the edge of the frontmovement-plate 6 and spread or swaged upon the back thereof, as at 7,whereby they are permanently fixed in thesaid plate. Of course, the saidpillars 2 may be permanently mounted in any other way in the frontmovement-plate 6, but the mode shown is effective and convenient. Thesaid positioning-pillars 2 thus permanently mounted in; the frontmovement-plate 6, are passed from rear to front throughpositioning-holes 8 in the front flange 9 of the center-ring or body 10of the watch-case as shown in Fig. 3, the said-holes '8 being made justlarge enough to receive the pillars 2 so that the pillars will beconfined against any lateral shake in the said holes.

Since the pillars 2 are mounted in carefully predetermined locations inthe front movement-plate 6, andsince the holes 8 are placed in carefullypredetermined locations in the flange 9 of the case-body 10, thepassingof the pillars through the holes, will accurately position the watchmovement with respect to the watch-case. It follows that in case thewatch is a stem-winding and stem-setting watch, the winding and settingdevices of the movement must, without any adjustment, fall into accuraterelations with respect to the winding-and-setting stem when the movementis inserted into the case. The winding-and-setting device may be of anyapproved construction and are therefore not shown or described indetail. The said pillars 2 are made long enough to project sufficientlyin front of the flange 9 so as to form a spacell between the said flangeand the dial 12 which is secured to the projecting, ends of the pillarsby screws 13 entering their outer ends as shown in Fig. 3. The space 11aforesaid, provides the required clearance for the dial work which isnot shown. It will thus be seen that the dial 12 is connected, not withthe case as is frequently done in watches of the cheaper class, but,through the pillars 2, with the movement itself, so that my inventionprovides for accurately positioning the dial with respect to themovement and the lineup thereof, or, to be more specific, to the centershaft and the seconds shaft thereof.

The movement having been positioned with respect to the case by means ofthe pillars 2, is fastened to the case by means of threefastening-screws 14 passing from front to rear through holes 15 in thesaid flange 9 of the case-body l0 and entering the thread- 1 ente ends ore m veme -pill rs 16 interposed between the front movement-p1 ate 6 andthe rear movement-plate 17 and'permanent-ly riveted at their front endsinto the plate 6. The rear ends of the said pillars 16 are. shoulderedto adapt the rear movement-plate 17 to be set over them and secured inplace in the usual manner by screws 18 as shown in Fig. 4. As shown theheads of the fastening screws 14 enter recesses 19 formed by strikingthe metal of the flange 9 inward around the holes 15 which, it will beobserved, by reference to Fig. 4, are made enough larger than the shanksof the screws 14 so as to provide clearance therefor, and leave thefunction of positioning the movement with respect to the case entirelywith the pillars 2.

In the construction shown, the case-body 10 is formed with a shoulder 20for the reception of a bezel 21 carrying a crystal 22. Upon its rearedge the case-body 10 is formed with a seat 23 upon which the caseback24 is snapped. The case-body 10 is provided with the usual pendant 25receiving the bow 26 which incloses the knurled crown 27 which restsupon the pendant 25 and carries the winding-and-setting stem which isnot shown.

Prior to my invention the fasteningscrews 14, or screws corresponding tothem, have been relied upon for fastening the movementin the case andpositioning it therein. Ihis practice has been found to be objectionableas the slightest variation in V the drilling of; the pillars 16 for thereception of the screws 14 would cause corresponding variations in theposition of the movement with respect to the case, and hence throw thewinding-and-setting'members organized with the movement out ofcorrectrelations to the winding-and-setting stem at the time of placingthe movement in the case. Under my invention, the positioning of themovement in the case is made invariably accurate for the reason that thesmooth positioning pillars 2 fit closely into the positioning-holes 8and entirely determine the position of the movement with respect to'thecase in which the movement is secured by the screws 14 which accommodatethemselves to the openings 15.

I claim 1. In a watch, the combination with a case provided withpositioning-holes, of a movement provided with positioning pillarspredetermined in position with respect to'the said positioning holesthrough which the said pillars pass and in which they fit to accuratelyposition the movement with respect to the case, and fastening-screwspassing through the case into the movement for fa s tening the case andmovement together.

2. In a watch, the combination with a case provided withpositioning-holes, of a movement provided with positioning-pillarspredetermined in location with respect to the said holes through whichthey pass for accurately positioning the movement in the case, and adial fastened directly to the proj ecting ends of the said pillars,whereby it is positioned with respect to the movement.

3. In a watch, the combination with a case-body formed with a frontflange provided with positioning-holes, of a watchmovement the frontplate of which is provided with forwardly projecting positioning-pillarspassing through the said holes for accurately positioning the movementin the case, and a dial applied to the projecting outer ends of the saidpillars for. securing it to the movement in predetermined position withrespect thereto.

4. In a watch, the combination with a case-body having a front flangeformed with positioning-holes and perforated for the passage through itof fastening-screws, of a watch' novement having front and rear.movement-plates, forwardly projecting positioning-pillars mounted inthe'said front movement plate and passing through the saidpositioning-holes in the said flange, movement-pillars mounted in thesaid front movement-plate, fastening screws passing through theperforations in the said flange and entering the outer ends of the saidpillars for securing the movement to the case,

and screws passing into the rear end of the said movement-pillars forsecuring the rear movement-plate thereto.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
